Waterproofing between shower pan and floor

Hi all,
The attached image shows the newly laid shower base.
I had to chisel some mudjob away to be able to fit in the new base.
As you can see, there is about a half inch gap between the shower base and the floor now. The edge of the floor is taped up to prevent crumbles from falling into the work area when we were positioning the base.

Should I do something to waterproof this gap? It's about an inch deep and then the plywood is exposed. It is possible that over time, some amount of water can drip into the location where the floor meets the base.

Can I spray some "Great Stuff" into the gap ?

Thanks
Tbone

You will caulk the gap between the tile and base to seal at the end of the tile installation. Fill the gap with speed finish patching compound before tile.

You can caulk or even fill with thinset or whatever portland product you have around. The floor will not be waterproof or is it supposed to be. To make it waterproof would require a couple more steps which is not usually done for bathroom floors. Caulk for sure to fill the grout space after the tiles are set.

Thanks JazMan. I filled it with floor patching compound this morning.
Thinset is a good idea - allows one to do it at the time of tiling.

Even with patching compound there is no reason to wait, unless the game is on soon.

LOL, yes! I am dry fitting the floor tiles now.
I think I'll get to actual tiling next weekend.
I will use the evening hours of this week to get the shower walls ready.
